From Junk Food, this officially licenced t-shirt was released in 2010. Like a lot of superhero t-shirts these days, it’s purposely faded to give it a vintage look. And it’s very difficult to find now, unfortunately.
The image is taken from the 1976 DC calendar.
DC used to publish annual calendars back in the 1970s, which featured new art from professional artists each month and fun things like trivia and puzzles.
This particular calendar is from 1976, and is included here because a bunch of Rogues appeared as the April pin-up.
Incidentally, if you’ve ever seen the list of DC characters’ birthdays, it comes from this calendar.
Another DC Heroes RPG book by Mayfair Games, this one from 1986.
